Revisiting this I cannot find flaws that derail the cool, leisurely pace that Edwards and Sellers establish up until say... the 41:00 minute mark when things start to flag the steady but now unsure narrative interest level.
But I remember and expected it to be more stuck in that time period, a curio instead of the great looking party atmosphere that you do feel as if you've somehow stumbled into.
Still great fun from a time when an actor in "Brownface was perhaps just that.
